Prometheus® Troy Bronze Clay is a claylike material which turns into pure, solid bronze when fired in a kiln. It is a mixture of micron sized bronze powder, water and organic binder. It can be formed by hand, rolled into a sheet or a rope. It can be molded, textured, even turned on a potter's wheel. Prometheus® Troy Bronze Clay can be fired with most lab-created gemstones (cubic zirconias), pre-tested natural stones, glass beads, ceramic and porcelain.
When the clay is fired in a kiln, the organic binder evaporates and burns away and you’re left with pure, solid bronze. Brush it, if needed pickle it to remove any firescale and finally polish.
You can create unique jewellery, ornaments, hollow ware, statutes, sculptures and many other decorative objects. Any thing you create with Prometheus® Bronze Clay is a piece of art. Combine it with your imagination and let your fingers do the rest!
For firing PTB®:
This is a 2-step-method.
Step.1 Place the dried piece (or pieces) on a stainless steel mesh and put it in to the cold kiln and let it raise to 500°C/ 932°F or put it on a kitchen stove. Fire it for 15 minutes, take it on to a fire proof surface and let it cool down.
Step.2 Put approximately 3 cm. of activated carbon to the bottom of a steel container. Place the pieces with at least 1.5 cm space between each other and fill the container with activated carbon, close it and put it into the preheated kiln to 850°C/1500°F. Let the kiln raise to the target temperature again and fire it for 90 minutes. When the firing is completed, either leave it to cool down in the kiln or, carefully take it out and leave it on a heat isolated surface until it is cold enough to take your pieces out.
